I think the problem was pilot error. I have now run the CCL tests with
the mpz_import patch without problems on the following Windows builds:
1) mingw64 x86_64 (MSYS2)
2) mingw64 i686   (MSYS2)
3) mingw32 i686 (mingw.org)
   This works after also applying commit 024d20f81e from master, needed
   to fix build problems (i.e. the problem will be fixed by merging into
   master, or rebasing the bignum branch).

I have not tried a 32bit wide int build, but I would expect that they
should work given that (1) works.
